Erich von Daniken has spent a lifetime gathering evidence to prove that before the dawn of recorded history our ancestors were visited by an alien race. Erich Von Daniken was responsible for popularising the ancient astronaut hypothesis of human development. Orthodox historians have been sceptical but a vast public have been drawn to his ideas by instinctive interest and wonder. His 26 books have sold over 60 million copies, in over 40 languages.
